SPECIFICATION i'ofming part of Letters Patent No 339,142, dated April 6,1886.

Application tiled July 3l, 1128-1.

To all 1071/0712, it may concern:

Be it known that I, JosEPn l?. BULLock, of Milwaukee, in the county of Milwaukee, and in the State of \Visconsin, have invented cer- 5 tain new and useful Improvements in Grain- Binders, and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to grain-binders, and

1o will be fully described hereinafter.

In the drawings, Figure 1 is an elevation of the rear end of a binder embodying my invention. Fig. 2 is a section of a portion of the lilik that connects the main wheel on the i5 tyerbperating shaft with the crank -arin of the needle-shaft. Fig. 3 is an elevation of the compressing and tying mechanism as seen from the front end of the machine while the packers are accumulating grain upon the conizo presser and the needle is at rest. Fig. 4 is an elevation of the needle and mechanism for tripping it into action. Figs. 5, ti, 7, and 8 are details of parts of my device. Fig. 9 is an elevation of the parts shown in Fig. 3, but

25 from the rear end of the machine. Figs. 1t),

11, 12, 13, and 14 are details showing the connection between the compressor-spring and eompressorarm. Fig. 15 is a detail view showing the position ofthe needle and trip-arm 3o or compressor, the latter being shown in dotted lines when the bundle is just ready to be discharged, and said trip arm or compressor in full lines immediately after the discharge of the bundle. Figs. 16, 17, and 18 show va- 35 rious positions of the needle and compressor after discharging.

A is the needle-shaft, on the driving end of which it carries a clutch-trip stop, A, which acts to trip the clutch connecting the pinion 4o a with the driving-shaft A2, the driving-shaft being connected by gearing a a2 with the large gear-wheel as on the tyeroperating shaft. The needle-sliaft also carries a crank-arm, A3, the outer end of which is connected bya link,

4 5 b b', with the rim of gear-wheel a. This link is made in two parts, b b, and awrist is bolted to the gear-wheel a3 passes through an opening made for itin head part, b, and bears upon a block and spring, 11"', as shown in detail, Fig.

2, that in turn is supported by a plate, b, and screws that pass through plate 1f into flanges If b* on the head b, and thus the connection between the wheel u and needleshaft is made yielding. The clutcli-trip stop A has a hub, l, that works loosely on the ncedle-sliaft,a1id this hub has formed upon it a lug. 2, from which an arm, 3, projects parallel with a tlange, 4, on the boss 5 on the frame, through which thc needle-shaft passes, and an adjustingscrew, G, passes through a threaded opening in arm 3 andimpinges against fiange 4. The needle U is keyed to the shaft A,and a bell-crank, C, is slipped loosely onto the shaft A and lies close up against one side ot' the needle. This bell-crank has a lug, C, on its upper arm,that protects beneath the back edge of the needle, and the lower arm of this bell-crank O has bolted to it the two-part trip-arm I), the bolt d, that secures them, passing through curved slots d' in the triparin, by which the angle of the arm l) to its supporting bell-crank mayY be adjusted to give bundles of dilfcrent sizes. The buttends of the parts forming the tripnrm are concaved to tit snugly against. the needle-shaft. E is one of the tubular supportingebars that tic the binding-frame to the harvester, and to this bar, at a point about undertlie trippingarm, I secure a bracket, l', by a bolt, e. This bracket has two lugs, c" e, projecting from it, to which I hang a frame, F. This frame is also connected with a lug, e, on bracket E, below its hinge, by a spring, E?. The frame F carries a sliding plate, f', to which a catch, F', is secured after it has been passed down 85 through a spiral spring, j", and the headf2 of this catch stands in position to engage with the inner end ot' bellcrank O'. The frame F has a lug, g, that projects up from it parallel with the catch, and to this is pivoted 9o a finger, g', the free end of which is slightly curved and provided with a shoulder at gz. This finger also carries a spring, g, that projects beneath the needle-shaft, and has a tendency to hold it down on said shaft, as shown, 95 for instance, in Fig. 18 of the d rawings. The

hub of the needle is provided with a lug, c, for the finger g to engage with when the needl is on its return.

The operation of my device is as follows: \Vhen the needleis at rest and is just ready to start, it is in the position shown in Fig. -t in dotted lines, its back edge resting upon lug C? ofthe bell-crank C. Hereit rests untila sufficient amount of grain has been accumulated upon the compressor trip-arm l) to overcome the weight ofthe needle, which, as before stated, is borne by the lug C2 on the bellcrank C', and when this occurs the needle will be started forward far enough to partially revolve its shaft, and through it lift the clutchtrip stop A', so to free it from the clutchpawl Il on a pinion, a, loose on the drivingshaft, and by connecting the pinion to the shaft thus throw the machine into operation. After this the weight of the accumulating grain as it is packed against the compressor will he taken by the catch F until the needle has encircled the gavel and has taken the twine into the knotter, and by this time the lugal on the hub ofthe needle will have passed under the fingerg and bey ond its shoulder. Therefore, as the needle returns after tying the knot, the lug c will abut against the shoulder gf, thrust the finger back to throw the head fi' of catch F out of engagement with the end of the bellerank C', which,when released at thispoint, will permit arm l) to fall into the position shown in full lines, Fig. l5, as the bundle is discharged.

To prevent the cord from entanglinf.; with the packer adjacent to it, l provide a shield. l, which I secure to the upper end of beam K in such a position as to extend down between the line of travel of the needle and packer points. The clutch-trip stop A and crankarm A lie at an acute angle to each other, and are connected midway of their length by a strap, A4, which is slotted in its lower end to take a securing-bolt, A6; and when it is desired to make the trip more or less sensitive the bolt A is loosened and the adjustment made by means of adjusting-screw 6, after which bolt A6 is again tightened.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combinatiomwith the needlehaving a lug at or near its hub, of the bell-crank carrying the compressor upon one arm, a springcatch for engagement with the inner end of the other arm of the bell-crank while the bundleis being compressed, and a linger connecting the lug of the needle with the frame ofthe springcatch,for tripping the bell-crank and allowing the compressor to fall, as and for the purpose set forth.

2. The frame F and the bracket to which it is pivoted, in combination with spring El, spring-catch F, arm l', finger g', needle having lug c, and compressor, as and for the purpose set forth.

3. The combination ofthe frame F, bracket E', spring Ff, spring-catch F', arm C', finger y', and spring y, as and for the purpose set forth.

ln testimony that l claim the foregoing l have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of XVisconsin, in the presence of two witnesses.
